Stuck at 99% indexing

Lesha_Cat · April 29, 2020, 2:03am

I have noticed my explorer is indexed but always missing one or two blocks because they are always being mined so the warning shows at the top:

99% Blocks Indexed - We’re indexing this chain right now. Some of the counts may be inaccurate.

I am trying to find an ENV var that will make it so it only shows the warning if it is behind by more than X number of blocks…

Closest I have found is LAST_BLOCK but the block height is always changing… Can I put something like minus 2 here to say blockheight minus 2?

Or is that the wrong setting and will stop indexing all together even when new blocks are mined?

Thanks

What you can do in that case, you can re-define finished_indexing? function:

github.com

poanetwork/blockscout/blob/0b47f9b6b0bd263035d6732801a6bef4da7aca2f/apps/explorer/lib/explorer/chain.ex#L848


    |> Decimal.mult(gas_used)


  {:actual, fee}
end


@doc """
Checks to see if the chain is down indexing based on the transaction from the
oldest block and the `fetch_internal_transactions` pending operation
"""
@spec finished_indexing?() :: boolean()
def finished_indexing? do
  json_rpc_named_arguments = Application.fetch_env!(:indexer, :json_rpc_named_arguments)
  variant = Keyword.fetch!(json_rpc_named_arguments, :variant)


  if variant == EthereumJSONRPC.Ganache do
    true
  else
    with {:transactions_exist, true} <- {:transactions_exist, Repo.exists?(Transaction)},
         min_block_number when not is_nil(min_block_number) <- Repo.aggregate(Transaction, :min, :block_number) do
      query =
        from(

In order to hide the warning, this function should return true. As a temporary solution you can do like this:

def finished_indexing? do
 true
end

Meanwhile, we should more properly handle indexing status in this function excluding from considerations the last X blocks as you mentioned.

Yes if we could look at that function in future blockscout releases, it should end up making it into the forks down the line at some point.

I will make that patching now, thanks!
